KNOGKDOWN ADJUSTABLE PICTURE-FRAME.

Specification of Letters Patent.

Patented July 26, 1910.

Application filed June 4, 1969. Serial No. 500,216.

To all whom it may concern:

Be it known that I, EDWIN J. DREISBACH, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improved Knockdown Adjustable Picture-Frames, of which the following is a specification.

My invention relates to an improved knock-clown adjustable picture frame, and it consists in certain details of construction to be more fully set forth in the following specification.

To enable others to understand my invention, reference is had to the accompanying drawings, in which:

Figure 1 represents the front face of one of the locking corner pieces of the frame, broken view of two of the side rails, and broken view of the glass; Fig. 2 is a similar View but reversed; Fig. 3 is a detail reverse view of'one of the corner pieces; Fig. 4 is a detail end elevation of one of the corner pieces looking in the direction of arrow a of Fig. 3; Fig. 5 is a detail broken side elevation of one of the side rails; Fig. 6 is a detail end elevation of one of the side rails looking in the direction of arrow Z) of Fig. 5; Fig. 7 is a plan view of the blank for the corner locking pieces; Fig. 8 is a broken of two of the side rails showing the position of their ends with respectto each other when the frame is assembled.

The peculiar feature of my improved frame is that the side rails are not mitered at the corners, as such corners are left open, and these open spaces are filled with specially designed corner pieces. The advantage of such a construction is that a frame of any size can be readily put together by simply cutting off the ends of the side rails to suit the size of the glass required for the picture. The sizes of glass on the market run as follows: 5X7, 7X9, 8x10, etc.; there fore, all that is required is to select the proper size of the glass to suit the picture and cut off the ends of the side rails to make the frame.

Referring to Figs. 5 and 6, the side rails 1 of the frame are made of sheet metal folded over on one edge to form the rabbet 1 as a supporting base for the mat and picture (not shown) and the glass2 and backing 2, shown at Figs. 1 and 2, 3 are the holding clips integral with the rail and adapted to be folded over against the backing when the frame is assembled. The corner pieces 4 are also made of a single piece of metal and first blanked out in the form shown at Fig. 7, and then folded on the dotted lines 0 (Z c f into the form shown at Fig. 3, leaving the space 5 (Fig. 4) for the insertion of the side rails and the opening it c' for the insertion of the clips of the side rails. hen the side rails are inserted into the open ends of the corner angle pieces, the leading clips, such, for instance, as the clips 3 (Fig. 2) will bring up against the shoulders 45 and 4 (seen more clearly at Fig. 8) to limit this inward movement of the rails and also determine the size of the frame by reason of the fact that, as the distance from the front edge of one clip to the front edge of the next clip (see also Fig. 5) is one-half inch, it follows that, as the glasses vary in size, preferably in half inches, all that is required is simply to cut off the ends of the rails close to one of the clips. hen the rails are seated in the corner pieces, their ends g (Figs. 2 and 8) will stand at right angles with each other and only approach or approximately approach each other at the corners of their inner edges, which corners will form the apex of the angle.

lVhen the rails are inserted or telescoped in the angular corner pieces, the clips 3 next to the end clips 3 are bent back upon the corner pieces and the clips 4 of the corner pieces are folded over upon said side rail clips, thus securely and firmly locking the rails and corner pieces together. The glass, picture and mat, together with the backing, are then laid on the rabbets and the clips 3 are folded over against the backing. Each of the clips 3 is provided with the holes 7 to which a wire or cord may be attached to any two of them, whereby to hang the frame.

The main feature of my invention consists of the side rails provided with picture holding clips; corner pieces to receive the ends of the side rails; stops on the corner pieces to locate the inward adjustment of the side rails; clips or like means on the corner pieces to engage with one of the clips of each of the side rails to lock said rails to the corner pieces. The clips of the side rails being located a predetermined distance apart so that, when the side rails are located by the stops of the corner piece, one of the clips of each side rail will be in position to interlock with one of the clips of the corner piece.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. A metal knock-down adjustable picture frame comprising side rails assembled to form open corners for the frame, angular corner pieces adapted to receive the ends of the side rails, a stop to locate said rails in said corner pieces, and clips integral with the rails and corner pieces for locking said rails and corner pieces together, said rail clips also adapted to retain the picture in the frame, for the purpose set forth.

2. A metal knock-down adjustable picture frame comprising side rails having picture corner pieces having stops for locating the inward adjustment of the side rails, and

clips adapted to interlock with one of the clips of each side rail and thus hold said side rails firmly against the stops of the corner pieces.

Signed at New Haven in the county of New Haven and State of Connecticut this 21st day of May A. D. 1908.
